Ocular Myositis in a Patient with Crohn Disease and Autoimmune Thyroid Disease

Abstract

Orbital myositis is defined as inflammation of the extraocular muscles often also involving the intraorbital soft tissues. There are a number of possible causes: differential diagnoses include thyroid ophthalmopathy, orbital myositis secondary to systemic autoimmune disease (including Crohn disease), or idiopathic orbital pseudotumor. Other causes such as orbital cellulitis, cavernous sinus thrombosis, arteriovenous fistulas, lymphoid tumours, lymphangiomatosis, sarcoidosis, and metastatic carcinomas should also be ruled out. The authors present the case of a patient with acute asymmetric painful orbitopathy with a history of both Crohn disease and autoimmune thyroid disease.
